Development and evaluation of a mental model forming support ITS-the qualitative diagnosis simulator for the SCS operation activity

We built an educational Qualitative Diagnosis simulator (QUAD) to model SCS (Space Collaboration System) conferences. Our research aim is supporting SCS beginner users in forming correct SCS mental models and in understanding SCS essentials. Therefore, we use a logical circuit, to model the possible computations. The system diagnoses the student's conceptual understanding mistakes about the SCS system and explains their cause.
